Smart thermostat installation in Plymouth
Your request goes to heating engineers covering Plymouth who check the boiler, fit Hive, Nest, tado or smart valves, and show you how the app works.
Smart controls are one of the measures listed under Plymouth's Warm Homes: Local Grant. Even without a grant, a smart thermostat is a low-cost way to cut heating bills in the 80.9% of Plymouth homes on gas central heating.

Compatibility
A combi boiler needs a heating-only smart thermostat. A regular or system boiler with a hot water cylinder needs a dual-channel model that schedules hot water as well, such as the hot water versions of Hive or tado.
If your boiler supports OpenTherm, a compatible thermostat can turn the flame up and down rather than just on and off, which saves a little more gas. The engineer can check your model.
Electric heating
Electric heating is common in Plymouth's city centre, at over a fifth of homes in St Peter and the Waterfront ward. Standard smart thermostats don't control storage heaters. Look for modern heaters with built-in smart controls, or ask an electrician about compatible systems.
Zoning
In Plymouth homes, smart radiator valves give each room a heating schedule of its own. They're useful in larger semis and in HMOs where tenants keep different hours.
Landlords
In shared houses, smart controls let landlords set a sensible maximum temperature and schedule while tenants adjust their own rooms with smart radiator valves. Check the tenancy agreement for how heating costs are shared before changing anything.
Tenants who want a smart thermostat should ask the landlord first, and keep the old one so it can go back at the end of the tenancy.
Settings that save
Ask the engineer to lower the boiler's flow temperature while they're there, and use away mode rather than switching off completely in cold weather. A smart thermostat that learns how long your home takes to warm up avoids wasting gas on early starts.
Plymouth homes and what they need
Interwar and postwar semis
If you still have a separate programmer and cylinder thermostat, a dual-channel smart controller replaces both and gives app control of hot water.
Victorian terraces on the hills
Hill-street terraces often have the thermostat by the front door, where cold air from the street skews the reading. Relocating it to the back sitting room, which a wireless unit makes easy, avoids overheating the bedrooms.
Waterfront and city-centre flats
Sutton Harbour and Barbican flats with a gas combi can use any mainstream smart thermostat, while those on storage or panel heaters need heaters that carry their own app control.
Areas covered
Engineers who cover Plymouth work across areas including Plympton, Plymstock, Mutley, Mannamead, Peverell, Stoke, Devonport, Stonehouse, Hartley and Saltash.
Questions people in Plymouth ask
Can I fit a smart thermostat myself in Plymouth?
Plug-in kits that replace a battery thermostat are simple DIY jobs. Anything that rewires the boiler or wiring centre should be done by a competent engineer, especially on older Plymouth systems with a separate programmer.
Can the Warm Homes: Local Grant pay for smart controls?
Smart controls are on the list of measures the Plymouth scheme can fund, usually alongside insulation or heating upgrades in an eligible home.
